Splitting strength perpendicular to grain for timbers using connections composed of steel pipes and high-strength bolts was experimentally evaluated. Edge distances influence the splitting strength; however, equations, which evaluate the strength and were developed in Japan and Europe, do not take into account the diameters of the bolts or pipes, nor edge distance. Fracture parameters Cr obtained in the experiment agreed with an existing equation. Variation of the splitting strength is greater and deformation capacity of the connections is smaller with respect to smaller edge distances.
